One of the types of objects in Praat. A Formant object represents spectral structure as a function of time: a formant contour. Unlike the time-stamped FormantGrid object, it is sampled into a number of frames centred around equally spaced times, Each frame contains frequency and bandwidth information about several formants.

Inside a Formant object

the time associated with the first frame, in seconds. This will usually be in the range [xmin, xmax]. The time associated with the last frame (i.e., x1 + (nx – 1) dx)) will also usually be in that range.

framei, i = 1 ... nx

the frames (see below).

Attributes of a formant frame

Each framei contains the following attributes:

intensity

an indication of the maximum intensity (a squared sound amplitude) in this frame.
